Specification of Letters Patent.

Patented-July 21, 1908.

Application led October 22, 1906. Serial No. 339,984.

- cago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Calculating-Machines, of which the follo. ing is a specification.

My invention relates to calculating machines including typewriter attachments and the object of the invention is to provide a novel and useful form of automatic mechanism which may be positioned before the beginning of any particular operation or problem, for determining Whether or not thetotalizer shall be operative or'non operative in any particular column and if operative, in which direction, addition or subtraction.

The machine here shownis similar in many respects to the ones shown and claimed in four previously filed patent applications for calculating machines; to wit:

275,780, filed August 25, 1905; 292,932, filed December 22, 1905;

313,070, filed April 21 1906; 326,081, filed July 13, 1906.

In the present machine there is a laterally fixed differential mechanism and a traveling totalizer or columeter as in applications The novelty in the present case resides in the mechanism for transmitting motion from the dierential mechanism to the totalizer and in the means whereby this transmitting mechanism is oontrolled. i

Referring to the accompanying drawings which form a part of this specification: Figure 1 isa general front view of a typewriter having attached thereto calculating mechanism embodying the invention. Fig. 2 is a plan view intended chiefly to show the transmitting mechanism and controlling means therefor. Fig. 3 is a front elevation ofthe parts shown in Fig. 2. Figs. 4 and 5 are sectional views taken respectively on lines'4-4 and 5 5, Fig. 2.

Arana onirica.

Similar numerals refer to similar parts throughout the several views.

The typewriter shown is of a well known pattern and has a stationary framework 1 and a traveling carriage 2 and keys 3. Said keys in addition to operating the printing mechanism (which is not illustrated as it forms no art of the present invention) operate the differential mechanism 4 which` may be of any suitable construction, for example as shown in Patent No. 782,554, granted to me March 7, 1904. By means of the differential mechanism movement is im arted to the shaft 5 in pro ortion to the va ue of the key depressed. aid shaft is permanently gear connected to the gears 6 and both the shafts and gears 6 may be considered as being a portion of the differential mechanism.

The construction of the totalizer is not an essential feature of this invention. If a machine is desired in which the operator is to have the choice only as to whether the Inachine shall operate or not operate the totalizer need not be reversible but a machine is desired which shall be susoe y tible of the full benefit of this invention an the operator is to have the choice as to whether the machine shall addsubtract or not operate then the totaliz'er must be reversible. The totalizer here shown is reversible and its construction is identical with the one for which a patent was granted to me February 15, 1905, No. 782,605. It will be understood however, that other forms of totalizers may be employed Without departin from the s irit of the invention. The tota izer will be ereinafter described but for the present it is sufficient to say that it contains a set of receiving wheels 33 which operate the totalizer parts and are adapted to mesh with the setting wheels 8 asthe totalizer travels. ast them. The totalizers travel in unison wit the typeany suitable agency, for example, the arm 9 a l engaging the slide 10 which travels upon the guide bar 11.- Slide 10 has a rectangular bar 12 rigidly secured thereto upon which one or more totalizers a're rigidly fastened. The totalizers are preferably adjustable lengthwise of bar 12, but when once set, the totalizers move with the bar in a fixed path so that their controlling cams 25 may operate a certain controlling device hereinafter described. The setting Wheels 8 above mentioned are mounted upon shaft 13. To obtain the fullest scope of the invention they should be independently rotatable especially if a pluralit of totalizers is em loyed, but practical resu ts may be obtaine with some or all of said setting wheels rigidly secured to shaft 13 if said shaft is rotatable. In the referred construction shown, in which the w eels are independentlyrotatable they are loose upon the shaft and held in pro er positions laterally by means of the spacing collars 8a.

From the description thus far it Will be evident that when a figure key is depressed the typewriter carriage will be shifted and will bring the receiving Wheels 33 into mesh seriatim with any given setting wheel. This feature is common to previous machines. I will now describe the transmitting and controlling mechanisms which embody the novel features of the present machine.

Transmittz'ng mechanism.- on a platform 14 attached to any suitab e portion of the framework 1 is slidingly mounted a late 15. This plate is adapted to slide in a direction parallel to the axls of the setting wheels 8. 'lhe method of guiding plate 15 upon platform 14 is not important but the present construction em loys screws 16 secured to said plate and a( apted to travel within slots 17 formed in platform 14. On plate 15 are mounted two spur pinions 18 and 19 which are laterally oflset from each other to such an extent that the space between them is a trifle greater than the thickness of a setting wheel. These pinions are adapted to mesh with said setting wheels and the parts are so related that when the plate 15 is in one shifted position the pinion 18 will mesh with the setting wheel, and when said plate is in another shifted position the pinion 19 will mesh with said wheel and when said plate is in intermediate position neither of said inions will mesh with said setting wheel. inion 18 isl driven by gear wheel 6 and so also is inion 19, but the latter indirectly throug 1v the agency of an idle gear wheel 20. The wheels 18, 19 and 20 consequently constitute a reversing gear, the idea being that when a setting wheel is being driven by pinion 18 it will rotate in one direction and when driven hy pinion 19 will rotate in the opposite direction notwithstanding the fact that the gear Wheel 6 rotates always in the same direction. Whether the totalizer adds, subtracts cr does notl operate depends therefore upon the position of plate 15. I will now describe the controlling mechanism whereby plate 15 is automatically shifted.

Controlling 'mechanism-At the rear edge of plate 15 is a toothed rack 21 which remains permanently in mesh with the toothed segment 22L formed upon the shifter 22. Said shifter is pivoted upon a pin 28 fixed in platform 14 so as to permit segment .22u to swing in a horizontal plane and thereby shift the late 15. The means for rotating shifter 22 a out its pivot are analagous to the corresponding parts shown and described in the aforesaid patent applications, and comprise controlling pins 24 and cams 25. The pins 24, best shown in Fig. 2 and Figs. 4 to 8, are eccentrically set upon rectangular bases 26 adapted to be set in the rectangular pockets 27 in shifter 22 in any one of three positions so that said pins may occupy a position toward the rear or toward the front or midway between. A controlling cam 25 is formed upon the bottom of each totalizer casing 3() and adapted to engafe its respective pin 24 as the totalizer travels past. cam travels in a fixed path it will cause the shifter 22 to swing about its axis and the effect produced upon the shifter will depend upon what position the pocket. In operation, i the operator sets the pin in such a osition that it will lie toward the rear of lts pocket, the plate 15 will be caused to assume one shifted position, but if he sets the pin so it will lie toward the front of its pocket said plate will be caused to assume another shifted position, while if he sets the pin in an intermediate position the plate 15 will be caused to assume an intermediate position. Thus by setting the pin in the proper position in its pocket the operator may before he commences to actually operate the machine, adjust it so that the controlling device will at the proper time cause the machine to add or to subtract or not to operate the' totalizer.

As it 1s desirable when a plurality of totalizers are em loyed to have each totalizer governed in ependently, the shifter 22 is rovided with a row of pockets as shown in fig. 2, and the cam 25 is so located upon the bottom of the totalizer that it will engage only its own respective pin. VIn consequence, each totalizer may have a different effect upon the shifter and the effect which one totalizer produces will beindependent of the effect which a prior or succeeding totalizer produces..

The totalize71b`or the urpose or illustrating the invention, I wil now'brielly describe a suitable form of totalizer the parts whereof are shown in detail in Figs. 1() to 17 inclusive. As above mentioned they have been previously described in Patent N o. sacoa As the fpin occupies in its The totalizer shaft 29 is non rotatably supported in the totalizer casing 30. Upon this shaft are supported a plurality of sets or groups consisting of 'live principal parts, to

wit: the totalizing wheels 31, the carrying pinions 32, the receiving or accumulating wheels 33, the epicyclic pinions 34 and the intermediate Wheels 35. Wheels 31, 33 and 35 are all freely rotatable about shaft 29 with the exception of wheel 35a located at the extreme right to correspond with the units column. This wheel is rigid on the shaft and its function is to form a fixed basis or foundation from which the rotatable parts of the totalizer move their definite amounts.

In each group of parts 36 represents a disk like supporting piece which is splined to the shaft and has at its left ortion a cylindrical hub 36a which forms a caring Whereon the intermediate wheel 35 is freely rotatable. The pin 37 extends toward the' left from piece 36 and serves as an axle whereon the carrying pinion 32 is freely rotatable. Said carrying pinion has four longand four short teeth which alternate with each other as best shown in F ig.11. By means of the long teeth said carrying pinion is alternately locked and rotated by the locking ring 31a and carrying teeth 31b respectively of the totalizing wheel 31 at its right. The short teeth serve to make the left portion of the carrying pinion a complete eight toothed gear, and this left portion of the carrying pinion remains permanently in gear action with the internal gear portion 31c of the next totalizing wheel to the left,- by means of the gears 33, 34 and 35 hereinafter described. As the result the carrying action of pinion 32 is always transmitted to the next higher totalizing wheel 31. Each totalizing wheel 31 has a set of numerical figures on its exterior cylindrical surface and is suported by the contact of its internal cylin rical surface 31a (which constitutes the aforesaid locking ring) u on the cylindrical edge of the supporting isk 36, said wheels 31 bearing loosely upon their supporting disks so as to be freely rotatable in ependently thereof.

The accumulating wheels 33 are plain spur gears having a comparatively large central aperture so that they may set over and be freely rotatable upon the points of the teeth of the intermediate wheels 35. Said accumulating wheels are narrow and their teeth project beyond the circumference of totalizing wheels 3l, so that they may be engaged by the master wheels 13. The totalizing wheel 31d and supporting piece 36a (shown at the 'extreme left of Fig. 11) are slightly modified to impart a finished a pearance to the extreme left end of the tota izer.

Extending leftwardfrom each accumulating wheel 33 are two pins 33a which constitute axles whereon the epicyclic )inions 34 ;5 are freely rotatable. Said epicyclic pinions remain in mesh with both the intermediate i wheel 35 and the internal gear portion 31 of wheel 31'for transmitting rotation from one to the other. The aforesaid intermediate Wheels 35 are Wide faced spur pinions de- 70 signed to both support the accumulating wheels 33 and also' remain in mesh With the carrying pinions 31 and epicyclic pinions 34 at the left, and serve to transmit the carrying action of the carrying wheel to the epicyclie `pinion and thence to the next higher totalizing Wheel 31. As a result of the above described construction of the totalizer it follows that the accumulating wheels 33 are rotatable in either direction and when rotated in one direction will add and when rotated in the opposite direction will subtract.

In'the general operation of the machine the operator sets a pin 24 in such position in its shifter 22 that it will when engaged by the B5 cam 25 swing the shifter 22 about its pin 23 and thereby shift the plate 15 to such position as to kbring either the pinion 13 or the pinion 19 or neither 0f them into line with the associated setting wheel 8 when the totalizer 90 is opposite to such setting wheel. The depression of any figure key will therefore produce either addition or subtraction at that setting wheel or no motion.

Inasmuch as each totalizer has its cam 25 95 in a different relative position on the bottom of the totalizer casing any given totalizer will operate upon the pins in only one of the pockets of the shifter and hence different totalizers by preadjustment may be made to produce different kinds of effects upon this shifter; in other Words by proprely adjusting the controlling pins, the diderent totalizers as they pass a given setting wheel may be made to produce different results; for example one may produce addition, another sub-` traction.. With a plurality of setting wheels present as shown, a great variety of bills and accounts may be computed. l
